11 Claims.

The present invention relates to new and useful improvements in brooders and has for its primary object to provide, in a manner as hereinafter set forth, novel means for electrically heating and ventilating the brooder, also for keeping the floor thereof dry and preventing sweat in said brooder,

Other objects of the invention are to provide a brooder of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight, portable and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:--

Figure 1 is a bottom plan view of a brooder constructed in accordance with the present invention, a corner portion thereof and the curtain being omitted.

Figure 2 is a vertical sectional view, taken substantially on the line 22 of Figure 1.

Figure 3 is a plan view of a portion of one of the electric heating rings.

Figure 4 is a diagrammatic view of a wiring system which may be used.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a hover or canopy which is designated generally by the ref- ?5 erence numeral I, said canopy including an anticlinal roof 2, end walls 3 and side walls 4. The canopy i is supported in elevated position by suitable legs 5. Depending from the ends and sides 3 and G, respectively, of the canopy I, are curtains 5. It will be observed that the canopy I is of laminated, insulating construction.

Suspended on suitable hangars I beneath the roof 2 are electric heating units which are designated generally by the reference numeral 8. Each unit 8 comprises a reflector 9 including a truncated outer cone I and a relatively reversed inner cone I I. Mounted in the apex of the inner cone II is an electric socket I2 for the reception of an ultra-violet ray lamp I3.

Mounted in the reflector 9 on suitable brackets I4, between the outer and inner cones ID and I I, respectively, is an electric heating ring I of suitable metal. The current to the heating rings I5 of the units 8 is automatically controlled by a thermal switch I5 which is mounted in the canopy i on suitable supports H. The thermal switch It is provided with a suitable hand control I3 which extends through the roof 2. The reference numeral I9 designates a tell-tale lamp which is mounted in the roof 2 for indicating when the heating rings I5 are energized. The reference numeral 20 designates hand adjusted ventilators which are mounted in the upper portions of the end walls 3 of the canopy I.

In operation heat from the rings I5 is radiated and distributed evenly throughout the brooder by the reflectors ii of the units 8 in a manner to dry the floor and keep said floor dry. 01 course, in this manner the chicks are also warmed. Any moisture and odors from the floor will rise in a natural manner and pass out through the ventilators 2!). It will be observed that forced ventilation is eliminated, the heat being projected and distributed by radiation. This radiated heat does not depend on conduction through the air from the radiators and becomes effective heat only when it strikes the earth or floor and surrounding objects, including the chicks. This heat is then projected back up from the earth or floor and surrounding objects by conduction through the air, as distinguished from radiation by which it warmed said earth or floor and surrounding objects. Of course, some of the heat does go by conduction through the air due to the unreflected heat from the rings I5 themselves.

It is believed that the many advantages of a breeder constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:-

1. A brooder including a hover which has an an'ti-clinal roof, end Walls and side walls, ventilators mounted in the upper portion of the end walls, and a heating unit supported by the hover, said unit comprising a reflector including a substantially truncated outer cone and a relatively reversed inner cone, and an electric heating element mounted between the outer end inner cones, said heating element being substantially surrounded by free space, whereby substantially free movement of air around said entire heating unit is permitted.
